Spain's party culture is full of dancing and drinking. Gatherings begin late in the evening and continue after dawn and sometimes through the next night. But you don't have to go to Ibiza or Barcelona to enjoy parties that last a whole weekend. Just head to downtown Miami's Heart Nightclub. It's open every week Friday night through Sunday afternoon, but exactly when it shuts down depends entirely upon the energy inside. The three-level venue consistently books some of the best underground house and techno DJs in the world. The Miami crowd showers them in so much love that they've been known to play for six, eight, or 12 hours. The third-floor terrace allows the sun to peek through, offering dancers rejuvenation in the soft glow of morning. It's a total FOMO factory, so just catch on already and stop missing out.
